iwlwifi: mvm: Consider P2P GO operation during scan

A scan during active P2P GO operation, i.e., data traffic with
clients, can impact the throughput and latency of such traffic.
Thus, when scan is requested while there is an active P2P GO
and low latency is asserted:

- Ask the FW scan logic to respect the P2P GO activity during the
  scheduling of the scan operation to minimize the impact on the
  throughput and latency.
- Force scan to perform EBS before starting the scan to reduce the
  number of scanned channels.
